J ACK-SPOOL-STRIPPIN G MACHINE.

Application filed February 20, 1925. I Serial No. 10,670.

This invention relates to spool stripping machlnes, and more particularly to machines for stripping the waste rovings from or delinting jack spools used in wool spinning mills. In such mills the wool is carded and placed on the jack spools in the form of rovings, there being a number of such rovings on each spool. These jack spools are then placed in the spinning mule or jack and the rovings spun into yarn. When the 'rovings on the jack spool'become exhausted, the jack spool is removed from the mule or spinning machine, and replaced by another jack spool which is full of rovings. Before placing the nearly empty jack spools back on the carding machines, it is necessary to remove the remainder of the rovings from the spools. Hitherto, this has been effected by manual labor by cutting or tearing the rovings from the barrel of the spool. My invention consists in a machine that will automaticallyremove the remnants of wool rovings from the jack spool.

It is an object of this invention to provide spools as above described. v

It is a further object of this invention to provide a machine of this character which will deliver the waste wool vfrom the jack spools in the formof lintto a suitable point where it may be collected for subsequent use. C

It is a still further objectof thisinvention to provide a machine of thischaracter which will be simple in structure andreliable in operation. Other advantages and objects of my invention will be apparent from the following? description and drawn the drawings: 7

Figure 6 is a detail cross-sectional view thereof, the frame 10 of my machine is provided at each side with a longitudinal extension 11 supported on a leg 12. An inclined rail 13 issecured to each extension 11 by means of brackets 14:. Asjbest shown in Figures 1 and 3, the rails 13 support a conveyor which feeds the jack spools to the cleaning mechanism, and are provided at each end with I integral side flanges between which slide longitudinally adjustable bearings 15. A shaft 16 is mounted between each pair of bearings 15, and has a sprocketl. scoured thereto adjacent each end thereof. A chain 18 is carried by each pair of sprockets 17 and each chain is provided witha plurality of projections or lugs 19, which serve to engage the barrels of the jack spools and push thesame along before them, the lugs 19 on the two chains being aligned crosswise of the chains.

An upwardly projecting arm 20 is secured to each ofthe bearings 15 at the lower end of the conveyor by means of an integral collar which is adapted to fit over the outside of the bearing. These arms 20 areadapted to receive a jack spool and hold the same in place untila pair of lugs 19 come into position to engage the spool and carry it away.

The upper or discharge end of the conveyor is provided at each side with a drop-off block 21, similarly mounted on the upper bearings 15. The conveyor chains 18 are eachsupported intermediate their length by an idler sprocket 22, mounted on a stud 23 secured to rail 13. 7 u j A rotary carrier 24, provided with two diametrically opposed prongs 25, is mounted adjacent each'side of the discharge end of the conveyor, on a shaft 26. These rotary carriers 24 serve to pick up the spools from the conveyor deliver them into and force them along a guideway 27, which is formed by two spaced arms 28 and 29 secured to each side of the frame 10, and having between them a slot adapted to receive the projecting shaft of the-spools. A wire brush 30 is mounted on a shaft 31 adjacent the guideway 27, and in such a manner that Y the periphery of the brush will engage the barrel of a spool passing through the slot. The guideway is inclined sothat the, sp ools may be fed therethrough by gra ityanled when necessary by the prongs of rotary carriers 24: whirh are shown of proper length to force the spoolsby said brush,-

and the lower end of the guideway opens into a discharge conveyor 32 substantially similar in construction to the feeding conveyor 18, but having twice. as many ,spo ol.

engaging projections thereon. The purpose of this is to make sine that there will be The conveyor and35v secured to shafts supported by rails 36 inthe same manner as conveyor chains 18. Referring particularly to. Figure d, the

extension 11 is providedadiarent thedischarge. end of the conveyor 13with. two

vertical standards 37 and 33. viin arm..39 is pivotedto the end ot eachupper member 28 of the guideway Qifand is also pivoted toa. slottedarm 4:0. Each standard 38 is provided with a stud 41 which projects through the slot. in the arm l0, and the outer end of the-arm 4101's connected to a spring. 42 connected to the top of the standard 38.

The pivotal connection between arms 39 and ll) is provided with a stud 43 projecting throughaslot in the standarc ;This structure results in a pair of springactuated toggle arms which. serve to hold the spools and. guide them while they are being transferred from the conveyor l t to, the guidewayQT. .The arms will, engage. theoshaft of a spool coming up the conveyorand will be raised l)ll6l6l;)y,: GX6l'ting a downward pressure on the spool by reason of the actionof the springs 4:2. Tie arms 39 serve to hold thev spool firmly ;i n place on the rotary carriersfla and direct it into the guideway Q'T.

.Referring particularly to Figures 2 and 3, in which the drive. of the machine is shown, the brush shaft 31 is provided at one end with fast and loose pulleys 44and 5 respectively. A conventional shipper lever 46 is adapted to shift a belt-A7 .connecting with. an overhead countershaft or other source ofpower, from one to theother of these pulleys, thereby starting or ,stopping, the machine as desired. A pulley is keyed to the other end ot'shaft 31 .and drives a pulley d9 secured.to,.a.sha.ft 50 thru the medium of .a. belt 51.

The shaft ,50 is provided witha clutch 52, consisting of asliding member .53 keyed to the shaft, and amember 541: loose onv the shaft. A sprocket is also loose .onthe shaft 50 and is secured. to theloose clutch member .54. hen the clutch 52 is engaged, therefore, the shaft 50 will drive the w ch eventually drives the shaft shown most clearly in Figs. ,3-.and 6.

sprocket 55. The sprocket 55 transmits power thru achain 56. tov asprocket 57 loose onshaft- 31. An idler. sprocket '58 is used to guide the chain 56, and is mounted on a stud secured to frame 10. A pinion 59, also' loose onshaft 31, is secured to sprocket 57, and-drives it train of reducing gears A. sprocket 60 secured to the shaft 26 drives a chain 61. extending around an idler sprocket 62 and a sprocket 63 fast on jack shaft 64:. Jackshaftbt in turn drives (xinveyor 18 by neansiot chain-.65, and conveyor 32 by meansof chain 66, these chainspassing over suitable sprockets secured to, the respective shaft, and the. .(onveyors being operated preferably at thesame speed. It isobvious, of course, that thisdrivemay be varied to suit particular. circumstances, and any alterations made which may seem necessary or desirable.

Shaft QG is provided withnmeans for centering the spools on the rotary carriers, whichis shown .most. clearly in Figure 5. This consistsbf a .fiange 67 [secured to a collar .68 slidably mounted on shaft 26. The collar ,68 telescopes within; a-isecondicollar .69.,and. a- ;spring 70.te nds toaforce theiflange 67 towards. the rotary carrier 24. It is understood, of course, that-a cooperating flange 67, is provided foneach rotary carrierg24. Theuflang es 71 of the spool 72; are engaged ,by, the flanges (Bland the spool is thereby centered with respect to the, rotary carriers 24. flPhe prongsfiaof the rotary carriers 24. are desianedto engage the shaft 73 of the spool.
